METAL HOOP.

Specification of Letters Patent.

Application filed November 14, 1914. Serial No. 872,245.

To all whom it may concern.

Be it known that I, EDWARD I. BRADDOOK, a citizen of the United States, residing in Winchester, county of Middlesex, and State of Massachusetts, have invented an Improvement in Metal Hoops, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a metal hoop for barrels, tubs, pails and the like, and has for its object to provide an inexpensive, strong, and light hoop for the purpose specified. To this end, the metal hoop comprises a sheet metal member in the form of a substantially narrow continuous band having a fold to form a hollow bead, and also having a series of arms extended from the unfolded portion of said band, said arms being spaced apart and connected together by a wire member. The hollow bead contains within it a reinforcing wire, which for the best results has its ends welded together and to the hollow bead, and the ends of the latterare also welded together. The wire member, which connects the arms extended from the band, has its ends connected together to form a wire hoop and said ends are for the best results welded together. These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is an elevation of the upper portion of a barrel provided with a metal hoop embodying this invention. Fig. 2, a plan of the barrel and hoop shown in Fig. 1. Fig. 3, a detail in elevation and on an enlarged scale of a portion of the hoop shown in Figs. 1 and 2. Fig. 4., a view like Fig. 3 with the hoop curved to conform to the taper of the barrel. Fig. 5, a section on the line 5-5, Fig. 4. Fig. 6, a detail of the sheet metal member before it is folded to form the hollow bead. Fig. 7, a modification to be referred to, and Fig. 8, a detail to be referred to.

Referring to the drawing (t represents a barrel provided with a metal hoop embodying this invention. The metal hoop comprises a sheet metal member in the form of a substantially narrow continuous band 6, see Figs. 3 and 4, which is provided with a fold to form a hollow head 0, within which is located a reinforcing wire 03. The metal band Z) has extended from its unfolded portion a series of arms 10, which are separated by spaces 12 preferably of a width and shape the same as the arms 10. The arms 10 are connected together near their outer ends by a wire member 13, which may be secured to the said arms by tongues 14-, which are punched out of the arms and bent or folded over upon the wire 13, to leave the latter loose or free to permit movement of one with relation to the other. The sheet metal member 3) is bent into the form of a hoop and has its ends fastened together, preferably by electrically welding the ends of the bead together and the ends of the reinforcing wire (Z together and to said head, as indicated by 20 in Figs. 1 and 2, and the wire member 13 also has its ends secured together, preferably by electrical welding, as indicated by 21 in Figs. 1 and 2; The loose wire 13 is made longer than the wire (2?, so that when the ends of the wire 13 are welded or otherwise connected together, it will permit the lower portion of the sheet metal member to be enlarged in diameter, so that the completed hoop is in such form that it may be readily driven onto the tapered barrel, without subjecting to detrimental strain either the shect metal member or the wire hoop formed by the wire member 13. The sheet metal member Z) may and preferably will be made by cutting a sheet metal. strip, not shown, into duplicate blanks, like that shown in Fig. 6. In this manner a very material saving in the cost of the sheet metal. member of the hoop is provided for, as there is no waste of stock. In reinforcing the sheet metal member 7), the wire (Z is applied to the continuous upper portion of the said member, and the upper edge portion thereof is folded over upon. the wire after the manner represented in Figs. 1, 2 and 5, to form the hollow head. In practice, a plurality of sheet metal members Z) may be applied in succession to a continuous wire (Z, as represented in Fig. 8, so as to overlap and form a reinforced sheet metal member of substantial or continuous length, which is then cut up into strips or lengths, according to thesize or diameter of the hoop to be made from it, and the reinforcing wire cl may be secured in fixed relation to the hollow head when to the sheet metal member, or the ends of. the arms 10 may be folded over upon the wire 13 as'represented in Fig. 7. The sheet metal member with both wires attached thereto, is preferably given a curved form so that the beaded upper portion is no longer straight as shownin Fig. 3,v but is curved as represented in Fig. 4, which imparts to the lower portion of the sheet metal member a larger diameter than the beaded upper portion-when the ends are welded together .to form the hoop. The ends of the beaded upper portion of the sheet metal member are then. fastened together, preferably by electrically or otherwise welding the same'together'and at the same time welding the ends of the reinforcing wire d together and to the hollow bead. The ends 'of the wire 13 are also fastened; together preferably by electrically welding them together to form a continuous hoop, which greatly increases the strengthof the lower non-continuous portion of the sheet metal member. The above described hoop is not only inexpensive but is light and strong.

'18 together, as represented in Figs. 1 and 2, I but it is-not desired to limit the invention in this respect, as the ends of the wire 13 may Itis preferred toweld the ends of the wire be otherwise secured together. 7

Claims:v -1.

BRADDOCK.
